Sponges are best described as simple, multicellular organisms that belong to the phylum Porifera. They are characterized by a porous body structure, allowing water to flow through them, which facilitates feeding, respiration, and waste removal. Sponges lack true tissues and organs, and they primarily rely on the movement of water to obtain nutrients and oxygen. They are typically found in aquatic environments, both marine and freshwater.
